A latchup current self-stop methodology and circuit design, which are used to prevent damage in the bulk CMOS integrated circuits due to latchup, are proposed in this paper. In a bulk CMOS chip, the core circuit blocks are always latchup sensitive due to a low holding voltage of the parasitic SCR path. The proposed latchup prevention methodology and circuit design can detect and stop the occurr...

Pott, A. and M. Shriklande, t-Designs with few intersection numbers, Discrete Mathematics 90 (1991) 215-217. We give a method to obtain new i-designs from t-designs with j distinct intersection numbers if i + j 1 does not exceed t.

WinSRFR is an integrated software package for analyzing surface irrigation systems. Software functionalities and technical features are described in a companion article. This article documents an example application. The analyzed field is a graded basin (close-ended border) irrigation system. The event analysis tools of WinSRFR are used first to evaluate performance of the irrigation system and...

SiSMA (Simulator for Statistical Mismatch Analysis) is a CAD tool for the statistical analysis of analog CMOS integrated circuits affected by technological tolerance effects including device mismatch.

Product innovation is a process of knowledge and technology resource integration. This paper mainly researches the process and realization of product integrated innovation based on function. Several function integrated methods are presented, and the principle solutions are selected and evaluated based on extend effect model. The process model for product integrated innovation is proposed, which...

According to these high-tech Othellos, a cooperative approach and a faithful partner are indeed essential ingredients towards the allocation of the huge financial and R&D resources that are required to improve existing EDA technology and develop the new EDA technology that is badly needed as the challenges of nanometer IC designs become more complex. Adultery, besides being a serious relationsh...

A perpendicular array PA,(t, k, u) is a n(y) by k array A of u distinct symbols, which satisfies: (i) every row of A contains k distinct symbols, (ii) for any t columns, and for any t distinct symbols, there are precisely 2 rows with the given symbols in the given columns. Such a structure may also be described as a A-uniform, t-homogeneous set of injective mappings from a k-set into a u-set. A...

Object-orientation has rapidly become accepted as the preferred paradigm for large scale system design. There is considerable literature describing approaches to object-oriented design and implementation. However discussion of testing in an object-oriented environment has been conspicuous by its absence. At first sight it appears that decomposition of a system into a potentially large number of...

Two years later, we are on the verge of a breakthrough into Philips Product Divisions and now the spot-light is on testing. So far, we fabricated, tested, and characterized about 10 asynchronous IC designs. Recently, we developed a test method which is competitive with modern synchronous test methods in quality and test time [2, 3]. Tangram is poised for CAT success (and in need of a new catch-...

www.pharmaporta l .com ackaging is one of the largest industry sectors in the world, worth $280 billion. Consumer healthcare packaging represents 4% ($11.2 billion) of the packaging industry. As drug manufacturers approach the 21st century, they face a number of challenges that packaging can help them meet. A decade ago packaging often was an afterthought for many pharmaceutical companies, view...
